I know this isn't really survival mode, but I was playing around in creative to create a resource-friendly self-propagating chicken farm. When the chest fills up with eggs, it sends a hopper minecart to a dispenser up top that switches on a comparator clock when it's got eggs in it, launching them automatically. I want to see if I can get it to drown some of the chickens too and feed the products to a sorter, so that it will produce meat too instead of just infinite chickens.

Am I the only one who has a specific set of rules for torch placement when exploring caves so that I can trace my way back quickly? Every time I hit a section that's already explored I just turn around because it's total chaos.
